Forza Horizon 5 features daily challenges that unlock over time, giving you the chance to earn rewards, and progress through each season.

Forza Horizon 5 Phone Box Locations
The best place to find Phone Boxes in Forza Horizon 5 is in cities. Make your way down to Mulege, which is also where you'll find the Star 27 Mural. Once in Mulege, just drive around. The streets are littered with Phone Boxes to smash, just make sure to hit them with enough speed that they break. We've included an image of a Phone Box just in case you don't know what you're looking for. For breaking five Phone Boxes you will get a point towards your Seasonal Progress. Make sure to earn as many points as you can before the Seasons Change.
Silent Mode Challenge
There's another challenge called Silent Mode that tasks you with smashing 15 Phone Boxes. There are more than 15 Phone Boxes in Mulege alone, so you will be able to take down two challenges at once by heading there. For completing it you will get an Accolade Reward. You can see the location of Mulege on the map below:
